Thanks guys wide space there 30 to 100. Ok, so here is my theory. All my electronics is up front with the battery. Solar which is only a 30a and it is fused, the remote electronics, which is fused, batteries (not), and a 600w linear which is fused, I want to use a fuse as for the simple reason it will melt (ANL type of fuse) if there was a fire up front disconnecting the battery by doing so. Leaving everything disconnected, perhaps I'm really over thinking this. I was not going to use the fuse as a link for electric as so much I was going to use it as a fuseable fire link, but didn't want it to break before that point.
You think I being over cautious.

Chuck, that is why I can't use a breaker type.
